Ever since I did some tests with my 13700K with e-cores enabled and disabled I wondered now that we’ve got smaller cores to handles background tasks, is hyper threading necessary for larger p-cores especially when it comes to gaming. I tested 40 games from a wide variety of genres, game engines, and APIs to see what the impacts are like on a modern higher core count CPU from Intel such as an i9-13900K which utilizes this hybrid architecture. We investigate the potential factors behind these results, considering resource allocation, thread synchronization, memory bandwidth, game optimization, and background task offloading. This comprehensive analysis empowers you to make an informed decision on whether to enable or disable Hyper-Threading, tailored to your specific gaming preferences and needs.

The improved performance probably comes mostly from cache hit rate as no longer the threads push each others data out of cache.

With HT, when 2 thread works on the same data AND run on the same core (from the the same processus), it can increase a lot the performance. But as a developper view, wa cannot contains our thread into a specific core, it s the OS who choose, and yes, if 2 thread of different processus run on the same core, they share the L1 data cache, and increase the cache miss prpbability!

For hyperthreading/SMT in the modern architecture, each CPU core has at least 3 pipelines per core and several ALUs and 1 or maybe 2 FPUs. The primary pipeline has a fetch/decode unit. The secondary pipeline in an hyperthreaded/SMT core also has a fetch/decode unit to serve as a second thread. The tertiary pipelines are given hardware accelerated operations like superscalar operations. All of these pipelines share the ALUs and FPU(s) of the core. Given the low FPU count versus ALUs, games that utilize heavy FPU performance on the CPU may benefit from disabling hyperthreading/SMT to relieve the demand on the 1 or 2 FPUs available. The point of hyperthreading was making use of the secondary pipeline that executed the MMX, SSE, and other hardware acceleration instructions when such operations were not being called. The main pipeline will have data set up for a hardware accelerated function and when executed, the CPU firmware will issue a series of instructions (no fetch/decode stages) through an available secondary pipeline and do such data processing using the extra ALUs. Hyperthreading was about putting that secondary pipeline and extra ALUs to work when the applications don't use the related instruction libraries. Your performance improvements can come from adverse effects from sharing the various ALUs and few FPUs. Another improvement could be less thermal throttling from running less parts per core, allowing higher clocks. Many possibilities that need a bit of studying to figure out.

Very good test, but I would have liked to see BF2042. It's by far the most CPU demanding game around. It uses 17 threads if the CPU supports it, and I'm curious how the game would perform with most of those threads being put on e-cores with HT off. Historically, Battlefield games have benefited from hyper-threading.

Nicely done, you just forgot to mention lower temperature and power consuption when HT is off.

@@dakrawnik4208 - If you're overclocking a CPU, it requires whatever voltage it requires to be stable at that frequency. Turning HT off means the CPU requires less voltage to be stable at the same frequencies. Undervolting is really only a thing if you're running at a stock configuration. Once you overclock past a certain point, you will almost always need more voltage to run stable, not less, so I'm a bit confused as to why you would tell someone to undervolt an overclock. That's usually a recipe for instability.

If I had SMT on that static 4950 MHz would be impossible. But on the old i7 extreme I needed 1.44 vcore to run 4.8GHz, like the other guy said after you past a point on the V/F curve it's not possible to undervolt...

It would be great to show the cpu usage in the windows task manager additionally to the fps values in each game. From my perspective as a system integrator hyperthreading increases performance, when windows deals with more threads than virtual cores present; and sometimes decreases performance, when less threads than virtual cores present, especially in virtualization and database applications.

Great vid. This is good for anybody, not just gamers. Linux users learn about io scheduler. Given the fact the OS uses a single kernel instruction queue, I'm suggesting mostly smoke and mirrors for Windows users, and the game is gonna load the gpu with work. You could make gain simply by disabling as many services as possible, freeing up the kernel stack.

Tbf theyre not all created equally. AMD's implimentation is SIGNIFICANTLY better than Intel's in both performance and power efficiency. In fact it's essentially confirmed that Intel's upcoming arrowlake will ditch it from then on while AMD's rumoured to try 4 way hyper threading although thats less certain. Either way it makes sense as hyperthreading makes scheduling so much more complex when there's ecores and amd doesnt have to worry about that

I find your choice of 1080P very strange. Sure, I guess you were thinking that makes the games more cpu limited, but that's when HT might actually MAKE sense or at least not get in the way. My experience shows that HT off gives improvement in extreme GPU load high res gaming, for example I went from 86 in RE4 remake to 95 average, and to me, that's big. 13980HX with P cores @ 5.3ghz here and a 4090m.

First of all I want to thank you for your really interesting content. I've been looking around on this topic for months now and I want to share with you my experience since I don't have the possibility to afford a setup like yours. I think the 13900k is totally overkill for 1080p today so maybe you can't see so much difference because in both case the cpu is sleeping. If you have a car with 1000 hp and another one with 500hp both of the car are fine for going to the shop and buy vegetables ;) Maybe you should have tested 4k low as the 4090 could render easy lots of fps in both res but the cpu had to render double the image size at least than the 1080p or 2k. It could be interesting doing the same test with an 9900k or 10700k that are older cpu that are starting to fight in 1080p/2k competitive games that are cpu bound, with a 4090 to ensure there is no gpu bottleneck. Also, they don't have the P/E cores architeture so we can investigate if there could be a benefit also for old high core count CPUs. What I've notice in my research is that the single core speed is more important that the number of cores. If you have 12 core at 4.0ghz vs 6/8 core at 4.5/4.7, the higher clock speed do more fps in cpu bound games. Also, you don't have taken the cpu+gpu render latency that is a really handy parameter for competitive players. For example, you can play cs at 240fps, but if you have 10/15ms of latency, is a lot better playing at 180fps but with 3/4 ms. Disabling HT lower this parameter so much, so always with competitive game in mind it would have been very curious to observe how this parameter changed in this two scenarios. Finally, disabling HT you gain heat and power usage, so, with gaming and performance in mind you will have more room to overclocking. you could do this test 13900K stock -> power draw 300W 13900k HT disable -> power draw 230W (could be more) 13900 HT disable + Overclock until you reach the 300W power draw (the same as stock) With the last option, you should gain 200/300mhz on the P core and see all the benefit of disable HT. Hoping to have provided further points for reflection, thank you again for the content.

Currently only 3 minutes in video: hope this will answer... On a traditional cpu like i5 12400 is 6c12t always better with it left on, especially with browsers, medal capture, steam, game, discord all open while gaming with in game voip, and discord running.

I'm running a 13700k / 4090 and turning off HT made Hogwarts run smoother. Thanks for this video :)

I can only assume that having HT off (in some titles, and certain game engines) getting better fps as a result of power budgets being redirected into better performance of the P-cores and giving them better higher boosting clocks = higher fps.

Could also be from songle ecores from each cluster taking some load that hyperthreading would have because not only is an ecore much more performant than a hyperthread but theres also only a core to core latency penalty between ecores in the same cluster. The cluster of 4 all have to also share l2 bandwidth so ipc is significantly higher when loading up different clusters first and the scheduler does do this thankfully. I also tested this in a gamewith process lasso and found that two ecores of different clusters were significantly more smooth than one pcore at 5.8ghz with the ecores being at 4.5ghz. Usually its meant to be like 2.5-3ish ecores = to one p core especially in something like faming but just 2 were still noticeable ahead when using different clusters and as i saod, much less core to core latency penalty like that too

I didn't even need to watch the video to know the outcome. Hyperthreading is one of the most misunderstood technologies in the hardware space today. While it was very beneficial when we were on 1-4 cores it's given diminishing returns since then, and is pretty much obsolete today where 8 cores are standard. Especially when E cores perform many of the tasks that made HT most beneficial in the first place. It's no wonder Intel is dropping it in future generations. In today's CPUs where the biggest hurdle is fighting the laws of physics any way you can shorten that pipeline should theoretically be beneficial. This has me interested in what Arrow Lake will bring.

I've noticed significantly higher stable P core clocks with HT disabled on Raptor Lake. My 13900kf with a D15 and Asus Prime P is only stable at 5.5 Ghz all P core in games with HT on, but 5.8 Ghz all P core with HT off. My 13600k goes from 5.5 to 5.7 Ghz all P core stable with turning HT off. Although the 13600k also probably gets less benefit from turning HT off due to having fewer threads. It's worth checking out if you have a Raptor Lake chip.

Intel says that 14th series is up to 16% faster in metro exodus than 13rh due to optimization. Does 14th run it automatically without E-cores? 🤭😅

it's not about performance or speed. All games just crash when HT is enabled on 13900k. Devs aren't going to study on this old school tech and just told us to disable the e-cores.

Hyperthreading just adds to pc latency , I was running apex at 210-240 fps with it on with a i7-11700k and a 3070, after turning hyperthreading off I get a solid 240. I know the i7-11700k is a bottle neck for the 3070.

Right but you're more likely to see benefits from turning hyperthreading off on older hardware if it can manage the basics... Applying this only to modern current or just well as of a day ago recent generation high-end Intel consumer CPUs is kind of a waste in general as that's such a minor use case.. and as far as hybrid CPUs go.. the premise wasn't it's hybrid nature that was the problem so much as it was whether or not the hyperthreading mattered in the performance cores... Not that it matters, given this person was pointing out that there's a point in the architecture history where the scale goes the other way... Which is supplemental, not contradicting.@@Waldherz

Well, about the Hybrid architecture. People started asking if you could disable HT (in previous videos on this channel) since the total thread count is so high to begin with. I personally dont get why I would buy a modern high thread count CPU to then disable some threads. Just get a lower tier CPU instead.@@jakedill1304
